BENCH-PLANE.

SPECIFICATION forming part of Letters Patent No. 435,951, datedSeptember 9, 1890.

I Application filed July 29, 1889. Serial No. 319,130- (No model.)

To all ,whom it may concern:

Be it known that I, ARTHUR E. RUST, a citizen of the United States,residing at Pine Meadow, in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements inBench-Planes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in bench-planes in which the bit isadjusted by means of a lever; and the objects of myimprovement are,first, to provide a means of adjusting the bit of a bench-planelongitudinally, making it cut the thickness desired, and, second, toadjust the bit laterally, thus squaring the cutting-edge of the bit withthe face of the plane. Both objects are attained by the movement of onelever either longitudinally or laterally, each motion being independentof the other, as illustrated in the accompanying drawings, in which-Figure l is a side elevation. Fig. 2 is same as Fig. 1, being partiallyin section. Fig. 3 is a View of the adj usting-lever, showing itsbearing on the pin, and is also partially in section.

Similar letters referto similar partsthroughout the several views.

The body of the plane A is similar to that of other planes, and to it issecured a frame B, having an upward extension to receive the screw D andform a bearing or support for the pin F, upon which is pivoted a leverCin such a manner as to allow the lever C to be moved laterally as wellas on the pin F as a pivot. Thus the lever C may be given either of twomotions upon one bearing or pin F.

The lever C is provided with three extensions G, H, and I. The extensionIpasses through a slot in the bit J and through the hole a in thecap-plate K, as shown in Fig. 2, so that when the screw D is turned orscrewed into the threaded hole in the casting B one end of the screw Dwill bear against the extension H and move the lever C, which will movethe cap-plate K and bit J, making the cutting-bit cut a thicker shaving,or if the screw D be turned the other way or unscrewed the lower end ofthe screw D will bear against the extension G,thus1noving the cap-plateKand the bit J up, so that the bit J will cut a thinner shaving. If thecutting-edge of the bit is not square with the face of the plane, it maybe made so by moving the lever C laterally in the direction required.

What I claim as new, by Letters Patent, is

I11 a bench -plane, the hereindescribed mechanism for adjusting thecutting -bit longitudinally or laterally, consisting of ale- Ver one endof which (being the upward extension) passes through a slot in the bitand through a hole in the cap-plate, this lever being so made andpivoted in a suitable supporting-frame as to allow the other end ordownward extension to be moved in either of two directions upon onepivot or fulcrum to adjust the cutting-bit longitudinally or lateranddesire to secure ally, substantially as shown and described,

for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
